SPECIFICATION forming` part of Letters Patent No. 781,742, datedFebruary '7, 1905.

Application led June 4, 1904. Serial No. 211,216.

To /r/Z wlw/n it 71u01/ concern:

Be it known that l, H ERMANN ROMNDER, a citizen of the United States,and a resident of Milwaukee, county of Milwaukee, State of Illisconsin,have invented certain new and useful lm provenients in Tube-MakingMachines or Presses. of which the following is a specification.

My invention relates more particularly to machines or apparatus in whichunder simultaneous inliucnce of heat and pressure sheets or plates ofmaterial, generallyv in the form of two a more ply wood-veneer plates ofany desii-ed thickness and curvature, may be pressed and the overlappedportions thereofl forced into intimate union with each other to formpractically seamless hollow tubes which may be used for a great varietyof purposes.

The objects of my invention are to provide an etlicient, economical, andrapid machine of simple construction and comparativelyv low cost by theuse of which, first, the overlapped portions of substantially bent orcurved sheets or plates of material, as wood-veneer plates consistingeach of a number of layers of wood or wood veneer glued together underheat and pressure with reversed grain by means of any suitablewaterproof cementing compositionsuch, for example, as a compound of glueand potash--may be united and glued together under the influence of heatand pressure and by means of any suitable waterproof cementingcomposition applied to the overlapping parts, and, second, the saidplates of material pressed to assume and retain a curved form with acurvature of greater or less pitch, as desired, resulting in theformation of hollow tubes which are practically seamless and combinesimplicity and cheapness of construction with greatest strength anddurability and which may be used as pipes, conduits, or cylinders or forthe mantles of barrels, drums, and other like packages and for variousother purposes.

To these ends my invention consists in the Afeatures of construction anddevices hereinafter described, and more particularly set forth in theappended claims.

The preferred form of the invention is illustrated in the accompanyingdrawings, forming part of this specification, wherein like characters ofreference indicate like parts throughout the several views.

The drawings illustrate more particularly my improved machine as adaptedfor the manufacture of barrel-mantles; but l do not, of course, limitmyself to the production of this class of articles only, as the sameapparatus may also be applied for the purpose of producing tubes rfor agreat number of other purposes.

Figure l is a front elevation of a machine embodying my invention,partly in vertical section, showing a tube compressed between theextended inner block or core and the several press-plates. Fig. Q is avertical sectional view of a portion of the apparatus, showing the tubeloosely on the collapsed core and the outer press-plates in reversedposition,(whcn the press is open.) Fig. 3 is a vertical section on line:c ,r of Fig. l. Fig. et is a plan view showing the frame work,thehydraulic presses, and the wedge.

A is the framework, consisting chiefly of a suitable casing with a base,side and rear portions, and top plate forminga rigid structure which themovable parts are mounted on and connected to in suitable manner,preferably as hereinafter shown and described.

B, C, and l) are sections or sectors which together form the expansiblcand collapsible inner block or coreI on which the material to becompressed is placed in any suitable manner and which when expanded hasan outer circumference equal to the inner circumference of the finishedtube. The sector B has an extension E at its rear portion, by means ofwhich it is suitably secured to the rear portion of frame A, and thusbecomes rigidly connected thereto. The sectors C and Dare slidablyconnected with each other and with sector B and movably held in relativeposition to each other by suitable means, as pins or guiderods b. F is awedge horizontally movable between the said sectors B,U, and l),supported by the framework A and sector B, and arranged to reciprocatehorizontally by suitable means, as the cog-wheel e, suitably mounted onthe vframe A and meshing' with the rack or gear-rail (l, provided on therear portion of IOO wedge F, the said cog-wheel being actuated l bysuitable means, as pulleys M, from a source of power. (Not shown.) rPhesurface of wedge F facing the core -scction B is preferably straight orflat, correspondingto the meeting surface of sector B, and the surfaceof wedge lF facing the core-sections C and D is tapering, correspondingto the tapering meeting' surfaces of sectors C and D. By these meanslthe sectors C and D may be raised and lowered and the core expanded andcollapsed as the wedge F is moved forward and back, and the sectors B,C, and D and the wedge F may be provided With suitablelongitudinally-extending tongues and grooves c or other means to assurea uniform expansion of the core and a true alinement of the said movableparts.

G and H are pistons each adapted to be moved horizontally through theaction of Huid-pressure introduced into the cylindercasings I I, bothcylinders being fed by one press-fluid supply or feed pipe f, wherebyboth these presses operate simultaneously. The pistons Gr and H may bearranged to slide horizontally between the base and the top plate of theframework A in any suitable manner, as shown in Figs. 1 and Q, so as toprevent binding.

K is a v-ertically-reciprocating piston movable in cylinder-casing L,which is fed by a separate supply-pipe g, whereby this press may beoperated independently of the horizontal hydraulic presses.

The pistons G, H, and K, as well as the top plate `of the frame A, areprovided with suitable pres's-plates M, N, O, and P, integral therewithor detachably connected thereto by suitable means, as bolts or screws,each of the said press-plates having' a concave surface conforming tothe convex surface of the portion of the core facing each of the saidpressplates. Each of these press-plates M, N, O, and P and the sectorsB, C, and D is preferably hollow and provided with flues or openings RR, arranged to be heated by any suitable means, as electricity, gas,steam, or other means. In the drawings the press-plates and sectors areshown to be heated by means of steam entering through inlets it /z/ anddischarging through outlets e', whereby the pressing-surfaces may beheated to the desired degree to act upon the material a to be pressedand upon the waterproof cemcnting composition applied to the overlappingportions of the material to be joined under heat and pressure. Thesepress-plates M, N, O, and P and the said core-sections B, C, and D mayall be heated to a uniform temperature suiicient to heat the materialand permit the bending thereof to the desired form and the joining ofthe overlapping parts, or the core-sections may be heated to aconsiderably higher temperature than the press-plates, so much so thatthe surface of the material e exposed to the said core-sections willbecome charred to a greater` o r less degree, as desired. Vhen thuscharred on the inner surface, the tubes formed of this material may beutilized for mantles of liquor or wine barrels and packages or otherpurposes requiring charred surfaces. This material a consists,preferably, of a number of waterproof wood-veneer plates or othersuitable material with overlapped portions la, which are designed to beglued and pressed together between the pressing-surfaces of the pistonsand the core-sections under suflicient heat and pressure, continuedthereunder for a suiiicient time to enable them to set and becomevirtually integral with each other. the waterproof cementingcompositionwith which the overlapped portions have been coated binding themtogether to one practically homogeneous and seamless piece of material.Any suitable waterproof cementiug composition may be used for thispurposev-such` for example, as a compound of glue and potash.

Suitable means, as counterweights S S, resting' when released onbrackets Z Z, mounted on or detachably connected tothe framework A, maybe provided to return the pistons of the horizontal presses as soon asthe hydraulic pressure is released.

l/Vhen the material t isv intended to form a tube to be used as abarrel-mantle, suitable hoops fr fr and bung-plates s s may besimultaneously connected and pressed to said material, and in that caseI provide suitable recesses n n in the pressing-surfaces of plates M, N,O, and P to accommodate the hoops /1' i' and bung-plates s s, and inpractice I preferably place the material so onto the core that the hoopsand bung-plate are cemented to and cover the overlapped portions of themantle and are pressed together therewith by the vertical hydraulicpress.

The operation of my improved machine is as follows: The machine standingidle, the wedge F being in its eXtreme outer position, as shown indotted lines in Fig. 3, the core being in its collapsed position, andthe horizontal and vertical presses being open, as shown in Fig. 2, thematerial a required to form the tube is placed in position over thecore, the overlapping portions of the material having' previously beencoated with any suitable cementiug composition and the hoops i' i' andbung-plate .v having been tacked on or otherwise placed and held inposition on the material in case the tube is to be used as abarrelmantle.

The wedgeF is then moved forward' IOO lIO

by means of the cog-wheel c until it reaches covered by the curvedsurfaces ot the pressplates N and O against the inner core. Then thevertical press is started by operating teed or supply pipe y. whenpiston K, with its press-plaie P, compresses the bung-plate s and thehoops` r r and the overlapped portions'A ot` the material against thecoie and forces them into intimate union. rI heapparatus then stops andis allowed to stand, exerting this tixeil pressure until the overlappedportions ot' the material/i have assumed permanent union and thematerial becomes practically one continuous homogenous and seamless tubeimpervious to moisture and atmospheric intluences and thehoops r r andthe biing-plate s have also been glued to or otherwise united with thetube, it being understood that the press-plates M, N, O, and P and thecore-sections B, C, and D are sutticiently heated during the pressingoperation by means otl steam circulating through the tliies or chests RRor otherwise to bring aboiittlie desired result under simultaneous heatand pressure, and the tube may be charred to any desired degree on itsinner or outer surface, or both, by means ot increasing the temperatureof the pressplates )L N. O, and P or the core-sections l, t, and l), orboth` suiiiciently to accomplish this purpose. The vertical hydraulicpress is then opened, the piston K sliding downward ot' its own weightas soon as the Huid-pressure through pipe y is released. Then thehorizontal hydraulic presses are opened, the water-supply through pipefbeing sluit otl, the pistons G and H returning by means of theci'ninterweights S S or other means provided tor this purpose. Then thewedge E moves back to its previous outer position by the reverse actionot cog-wheel c, when the core collapses, and the tinished tube may thenbe taken trom theapparatus by lit'ting it trom the collapsed core, thesaid material f retaining the exactshape it has assumed between thepress-plates and the core-sections under heat and pressure and theoverlapped portions ot' the material having practically bef come onehomogeneous piece ot' material, the said material thus t'orming apractically continuous and seamless tube ot desired shape. lly insertingand suitably securing to the pistons and the traine A press-plates andcoresections having surt'aces with a curvature ot greater or less pitchthe same machine may be used tor Yt'orming and pressing' tubes withlarger or smaller diameter and ot' cylindrical, oval, or other desiredshape.

By means ot this machine I am able to torni two or more ply wood-veneerplates or other suitable material and unite the overlapped portionsthereof, so as to produce tubes suitable t'or pipes, conduits,barrel-mantles, or other structures ot' any desired shape and size inwhich curvature ot' greater or less pitch is desired and to char one orboth surfaces ot said tubes to a greater or less degree,

as may be required. when they may be used t'or any ot' the purposesabove stated necessitating charred surt'aces.

This invention is susceptible ot many modilications, and the details ot'operation and construction ot' this machine may be varied trom the abovedescription without changing the principle otl my invention so long assheets or .plates ot suitable material may be bent and pressed thereinto assume and retain a curved torni ot' greater or less pitch and theoverlapped portions joincd and torced into intimate union with eachother` so that the material will t'orm practically continuous andseamless hollow tubes. i do not, thcret'ore, limit this speciticationand the claims to the precise Jforms ot' the invention illustrated inthe drawings and hereinbet'ore described.
